Summary: This study focused on a case of babesiosis in a splenectomized patient in France, examining the genetic characteristics of the etiological agent named Babesia sp. FR1 in comparison to closely related parasites. The analysis confirmed the clear separation of B. divergens and B. capreoli, and identified Babesia sp. MO1-like parasites as a separate species with rabbits as its natural host. The natural host of Babesia sp. FR1 remains unknown.

Summary: Novel Piroplasmida clades and species were found in wild animals from Brazil. A putative new Babesia species was detected in capybaras and associated ticks through phylogenetic assessments based on distinct molecular markers. The phylogenetic analysis showed that this new species belonged to a new clade sister to the Babesia sensu stricto clade and the Theileria sensu stricto clade.

Summary: The glycotype at the fetomaternal interface was compared among endotheliochorial cat, lion, and dog placentae using 24 lectins. There was a high similarity in glycan expression between cat and lion placentae, except for the presence of terminal a-galactose in lion trophoblast. The dog showed notable differences, especially in the trophoblast, which may be attributed to species-specific glycotypes resulting from evolutionary divergence.

Summary: This study aimed to investigate the prevalence and risk factors of Piroplasma and Anaplasma species in animal hosts and their associated ticks in Egypt. The results showed a significant prevalence of piroplasmosis and anaplasmosis, with 23.08% of animals testing positive for pathogens DNA. Cattle were found to be co-infected with multiple species, including Theileria annulata, Anaplasma marginale, and Babesia bigemina. Tick infestation was identified as a potential risk factor for anaplasmosis, while no piroplasms were found in the ticks.

Summary: Longidorus sabalanicus n. sp., a new nematode species, is described and illustrated based on research on two populations from north-western Iran. Morphological, morphometric, and molecular studies were carried out to identify and differentiate this species from closely related species. The new species shows similarities to several other Longidorus species but has distinct characteristics and phylogenetic relationship with L. behshahrensis.

Summary: The strains of Drouetiella species from a terrestrial biotope in the Arctic and Subarctic areas of European Russia were isolated and characterized using an integrative approach. The study showed the morphological plasticity of Drouetiella species and identified a new taxon. The analysis of 16S-23S ITS rRNA sequences revealed differences in length and nucleotide composition, affecting the hypothetical secondary structures of certain helices.

Summary: Theileriae are intracellular protozoan parasites transmitted by ixodid ticks that infect both wild and domestic ruminants. Theileriosis causes significant economic losses in the livestock industry worldwide. The study in Russia detected Theileria parasites in cattle and found that they share a common genotype with other pathogenic strains from different countries.

Summary: This study investigated the diversity of heterolobose amoebae, focusing on a new species called Parafumarolamoeba stagnalis n. sp. from a small pond in European Russia. Using light and electron microscopy, as well as molecular phylogenies, the researchers described the fine morphology and evolutionary relationships of this new heterolobosean species.

Summary: A new genus Cryptochroococcus and a new species Limnococcus fonticola were discovered from the Qinghai-Tibet Plateau. Limnococcus, phylogenetically included in Chroococcaceae, is no longer a member of Merismopediaceae. The phylogeny based on the 16S rRNA gene revealed that genera associated with Chroococcus were monophyletic.

Summary: In this study conducted in Tchicala-Tcholoanga, Angola in 2016, a total of 17 tick species and 15 tick-borne pathogens were identified in domestic animals. The research also reported new records of certain tick species in Angola and provided important findings regarding the prevalence of various pathogens in cattle, goats, sheep, and dogs. These pioneering findings contribute to the understanding of tick-borne diseases in Angola.

Summary: Two black rhinoceros subspecies (Diceros bicornis bicornis and D. b. minor) in South African conservation areas are managed as separate metapopulations, with significant differences in occurrence of Babesia bicornis and other piroplasms. Rhinoceroses in more arid areas appear to be free of T. bicornis and B. bicornis, likely due to the absence of vectors. Appropriate prophylactic actions should be taken when individuals are relocated for metapopulation management purposes.

Summary: This study conducted a cross-sectional investigation on cattle in the Karamoja Region of northeastern Uganda, identifying 12 different tick species, some of which were previously unreported. Parasites that transmit diseases and uncommon pathogens harmful to cattle were detected in the vectors. The gathered information serves as an indicator for estimating potential disease transmission risks among cattle populations and to humans, aiding in disease control strategies.

Summary: This study evaluates the impact of cross-border transhumance on the spread of cattle ticks and associated pathogens, revealing variations in the distribution of tick species and pathogens at different time points during seasonal migration in Burkina Faso and Benin. The prevalence of pathogens was significantly lower at the end of the transhumance period, indicating the effect of tick population changes induced by transhumance and seasonal variation.

Summary: Ticks in Africa remain a major obstacle in the livestock industry due to tick-borne pathogens. This study conducted a systematic review and meta-analysis to examine the distribution and prevalence of these pathogens in African ticks. The highest prevalence was found for Rickettsia spp., R. africae, R. conorii, A. marginale, E. ruminantium, and E. canis. The prevalence of C. burnetii was low, but higher for Coxiella spp. and Coxiella-like endosymbionts. The study also identified the effect of tick genera, tick species, country, and other variables on the epidemiology of these pathogens in ticks.
